I have 2 PIR sensors that i want to use on my Raspberry Pi however both 5v's are being used and I'm left with the 3.3vs and am unsure if i am able to use it as it may damage the board? Here is a link to the sensor i am using.

    You can power multiple devices from one power pin.

You can create a 5V rail using a breadboard. If not that, then you can use a 9V battery and pass it through a voltage regulator like lm7805 to get the desired voltage. To create a rail, connect 5V to one of last two horizontal rows of your breadboard
